Abstract: 476,378. Typewriters. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD, V. W. July 21, 1937, No. 20217. [Class 100 (iv)] Carbon-sheet arrangements.-In a manifolding- attachment for use with typewriters and like machines and comprising a travelling carrier for guiding interleaved continuous webs and carbon sheets and having a track on which a carbon-sheet holder moves towards and away from the platen, the track is pivoted transversely to the carrier so that it can be tilted towards or away from the platen during the feed or withdrawal operation of the webs respectively. The carrier comprises a frame 1 mounted on rollers 2 and connected by slotted projections or other means for movement with the platen. Pivoted to the frame at 7 is an upper frame 1a, on which, on rails 6, runs a carbon-sheet holder 4. The front end of the frame 1a may be raised or lowered by toggle levers 8, 9 pivoted to the frames 1a and 1 respectively and operated by a lever 13. The paper webs are guided over a freely pivoted guide roller 3, between the carbon sheets secured by suitable means to the holder 4, between guides 21 and over a plate 20 to the platen. On its return movement the holder 4 passes over a trip 15, which then latches it against advance while the webs are drawn through the carbon sheets. When the frame 1a is lowered to recommence line-spacing of the webs and sheets, the trip 15, pivoted at 14 to the frame 1a, and with its forward end 17 engaging a bar 18 on the frame 1, is lowered out of active position.

IPC: A61K31/16
Filed: 1951-08-30
Abstract: A stable, substantially anhydrous (not more than 1, and preferably 0.5, per cent water), homogeneous liquid polyvitamin preparation comprises both water-soluble and fat-soluble vitamins in a vehicle consisting essentially of propylene glycol and a water-soluble polyoxy-alkylene oxide derivative of a fatty acid (not less than 12 C atoms) partial ester of a hexitan, said vehicle constituting the major proportion, preferably at least 80 per cent by weight, of the preparation, the propylene glycol being 0.5 to 2 parts by weight per part of the hexitan derivative. Polyoxyalkylene derivatives of sorbitan with acids such as lauric, stearic, palmitic and oleic, where the alkylene oxide is ethylene oxide or propylene oxide, present as 16 to 25 oxide groupings, e.g. "Tweens" (Registered Trade Mark), are preferred.  The "Tween" is preferably dried in vacuo.  One or more fat soluble vitamins are dissolved in the "Tween," the water-soluble vitamins are dissolved in the propylene glycol, and the solutions so formed are mixed, the operations being carried out in the presence of an inert gas e.g. nitrogen or CO2.  If the propylene glycol has not been previously dried, the vitamin preparation is dried over an agent insoluble in propylene glycol e.g. anhydrous sodium sulphate, anhydrous calcium sulphate or activated alumina.  In one example, vitamin A, vitamin D2, oil of limes and d-pantothenyl alcohol are dissolved in polyoxyethylene sorbitan mono-oleate at 50 DEG  C. under CO2. To this is added a solution of urea, nicotinamide, riboflavin, ascorbic acid, pyridoxine hydrochloride, thiamin HCl and saccharin at 50 DEG  C.  Other specified vitamins are vitamin A palmitate, vitamin A acetate, thiamine mono-nitrate and a -tocopherol acetate.

Filed: 1930-07-08
Abstract: 349,352. Cupping. FITZPATRICK, H. D., 94, Hope Street, Glasgow.-(Marquette Tool & Manufacturing Co. ; 1900, North Kilbourn Avenue, Chicago, U.S.A.) July 8, 1930, No. 20625. [Class 83 (iv).] The draw ring 15 of a cupping press is raised to working position by fluid pressure on a piston 18 supplied by a continuously working pump 25 from a tank 23 and when the piston 18 becomes jammed against the top of its cylinder the accumulating pressure raises a spring pressed valve 33 so that the fluid is byepassed from the pump back to the tank through the pipes 31, 35. When drawing begins, the cylinder fluid closes the flap valve 29 and opens the valve 38 against a set air pressure resistance through the pipe 46 to byepass the liquid through the pipe 40, 35 to the tank 23, thus maintaining a yielding pressure on the draw ring during working. At the end of the stroke, the valve 38 closes and the pump pressure raises the flap valve 29 to raise the draw ring again.

Title: Control devices for maintaining a predetermined pressure differential across a fuel metering device
IPC: F02C9/26
Filed: 1968-05-01
Abstract: 1,218,944. Gas turbine engine fuel systems. MOTOREN-UND TURBINEN-UNION MœNCHEN G.m.b.H. May 1, 1968 [June 10, 1967], No.20722/68. Heading F1G. [Also in Division F2] A control device for maintaining a predetermined pressure difference across a fuel metering device fed with fuel from a pump comprises a differential pressure piston subjected to the pressure differential and movable automatically to return a greater or lesser amount of fuel to the lowpressure side of the fuel pump to maintain the pressure differential, and a variable damping piston arranged between springs which act via a piston rod to apply a force to the piston, the force being variable by means of a fuel temperature sensor. Fuel is supplied to a gas turbine engine fuel nozzle 6 via a metering valve 11, the pressure upstream and downstream of the metering valve being applied to opposite sides of a piston 15 which controls a by-pass port 20 for by-passing fuel back to the inlet side of the fuel pump 9 so as to maintain constant the difference between the two pressures. To prevent instability, a damping piston 25 is interposed between springs 19 and 22 which load the piston 15, the damping effect being adjustable by means of an adjustable throttle 24. To compensate for variations of fuel flow caused by heating up of the fuel, bi-metallic elements 30 expand with increasing temperature to increase the loading of the springs 19, 22. The spring-loading can also be adjusted by a screw 37 to accord with the specific gravity of the fuel, the specific gravity being indicated on a scale 39. To eliminate the effect of static friction, the pistons 15, 25 are rotated through a drive connection 26, a thrust bearing 29 being provided to allow for the rotation.

Abstract: 403,164. Recording sound. MILLER, J. A., 4627, 193rd Street, Flushing, New York, U.S.A. July 25, 1932, No. 20955. [Class 40 (ii).] The constant-amplitude method of recording is adopted when mechanically producing sound records capable of direct optical reproduction The recording may be effected by means of apparatus in which the movable system, provided with a recording chisel having a V-shaped edge, is tuned to a high frequency. The track may be made either by cutting away parts of an opaque layer, together with parts of an adjoining transparent layer of gelatine or the like, or by cutting in a transparent layer and afterwards so treating the track or its surroundings that they are differentiated as regards transparency. The tuning of the cutter to a high frequency would produce a peak 3 in the frequency characteristic, but this is flattened out by damping. A peak 2 also occurs as usual in the low frequencies, and may be damped by electrical compensation in the amplifier. By this means, the resulting characteristic curve 4 shows substantially constant amplitude over a wide range of frequencies.

Abstract: 1328621 Making heat exchangers; soldering GRANGES ESSEM AB 19 April 1971 [5 Feb 1970] 20957/71 Headings B3A and B3R In the continuous production of elongate heat exchange elements (e.g. of copper or copper alloy) each consisting of a basic profile 14 to which is soldered at mutual points of contact a corrugated metal-foil strip 21, a production method comprises: (a) feeding along a continuous-movement path A a continuous length of the basic profile 14, (b) feeding together with the profile a continuous length of the corrugatedfoil strip 21; (c) cutting (e.g. at 43) said strip 21 into lengths in a repeated cycle; (d) placing said lengths into abutment with the profile, (e) soldering said lengths to the profile, and (f) cutting (e.g. by a device 20) the profile length into shorter lengths. As shown, the profile 14, comprising a copper foil strip coated with solder, is fed through a furnace 15 to melt the solder and then passes between continuously rotating rolls 17, 18 where the lengths of strip 21 spaced by gaps 45 are successively applied to the profile. The assembly continues its path through a cooling and holddown device 19 (where the solder is cooled to join the parts together) and is finally cut by a flying shear device into requisite lengths for the heat exchange elements. The strip 21 in its path to the appropriate roll 17 or 18 passes from corrugating rolls 22, 23 to and through a compacting arrangement consisting of roll pairs 29/30 and 32/33 rotating respectively at differing speeds so as to compress the corrugations in the direction of strip movement. The strip then forms a loop 40 (constituting a storage magazine) from which it passes to an intermittently rotated roll 41 being held thereto by suction. The periodic stopping of the roll 41 (under the control of a pulse counter 42) is to allow cutter 43 to sever the strip into predetermined lengths which are held to the roll by the suction and then released as they are transferred to the continuously rotating roll 17 (or 18 as appropriate). The relative rotation of the rolls also causes adjacent strip lengths to be spaced apart by the interval 45 on the basic profile 14.
